Couldn't you say the same for the Vietnam War? After the Tet Offensive, North Vietnam was reeling from it's failure to achieve its military objectives (it was an absolute success politically).
The US got North Vietnam to agree to a peace treaty and then left South Vietnam. Vietnamization failed and once the North Vietnamese realized the US wasn't going to help the South anymore, they just took the whole country.
